Integration with comments broke with recent versions

[Ten0]

Describe the bug

A few releases ago, it became possible to use VSCode Vim when editing comments from the Github Pull Requests extension.
This was absolutely amazing, and game changer when writing comments. (Vim ❤️)

However since a very recent release (of VSCode probably), pressing escape while in insertion mode, instead of returning to normal mode, cancels writing the comment, closes the dialog and discards the text.
In one hour of reviewing PRs, it's the 4th super detailed comment I have to entirely rewrite because it's hardwired in my brain that I can press escape to exit insertion mode, and that actually closes the comment dialog. (So by the way there's no way to exit insertion mode.)
I'm going crazy. 😭
Please help! 🏝️🏳️

Thanks in advance!

To Reproduce
Steps to reproduce the behavior:

1. Install VSCode VIM & Github Pull Requests extension
2. Open a PR
3. Start writing a comment
4. Enter insertion mode and write some text
5. Press escape.

Expected behavior
Exits insertion mode, not closing the dialog.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.28.1
